Sienna Tiggy Guillory was born in Kettering, Northamptonshire, England, on 16 March 1975 – her zodiac sign is Pisces and she holds British nationality. She’s an actress and a model who’s probably still known best for her portrayal of Jill Valentine, one of the lead characters in the 2004 action horror science fiction movie “Resident Evil: Apocalypse” written by Paul W. S. Anderson, directed by Alexander Witt, and which also starred Milla Jovovich and Eric Mabius. It follows Alice who has woken up in the Raccoon City hospital while the city she’s in is about to be bombed because it has been overrun by zombies.
